U.S. Senator Elizabeth Warren and several other lawmakers have raised concerns about David Sacks, the Trump administration’s AI and cryptocurrency official. The senators have sent a formal letter requesting clarification on his workdays and location since his appointment in January 2025.
Lawmakers are questioning whether Sacks has exceeded the 130-day annual limit for temporary federal employees. They also expressed concerns about potential conflicts of interest, noting that Sacks continues to manage his Silicon Valley venture capital firm, which actively invests in both AI and cryptocurrency sectors.
The inquiry follows a New York Times investigation into the Trump family’s cryptocurrency platform and a UAE AI chip transaction, in which Sacks allegedly played a pivotal role. Lawmakers fear that dual roles could undermine public trust and policy transparency, particularly given Sacks’s influence in shaping U.S. AI and crypto regulations.
The senators have requested detailed records of Sacks’s official work schedule and compliance with federal employment rules. The matter is expected to spark further debate on the intersection of private investment interests and public office responsibilities in the fast-evolving AI and cryptocurrency industries.
